My new CCTV camera required a 256GB card. Found this site and was delighted with price and service
Seems to work fine in my Android smartphone. Doesn't need to be ultra-fast for the backup/extended storage required, though seems to copy/import data fast enough anyway. Received very promptly as expected, and well-packaged.
Seems to work okay, will give it a bit of time.
Excellent and quick service.
The SanDisk memory card arrived promptly, was easy to install and works perfectly. I would recommend as extra memory for an android phone.
